Small rust patches - What do I need?
« on: 21 April 2011, 09:20 »
Tomorrow some major areas of rust on my car will be removed and replaced with new parts/metal, however I want to get rid of the small rust patches around the car, such as the top of the windscreen, patches on doors and anywhere else that may need doing.

These patches aren't very big but are noticeable, so how would I best go about doing this?

Preferably I don't want to use any big tools, I'd rather do it by hand if I can. I don't need to worry about paint as the whole car will be matte finished soon, so I'm just wanting to get the small areas sorted before this is done.

What do I need? Sand paper? What grits? Filler maybe? Kurust? Zinc primer? I need to buy this all today so if someone can point me in the right direction it would be greatly appreciated.

Cheers.

As a wise man once said:

  • grind the area back to metal - take your time doing this and do it gently
  • treat the metal with rust stuff like kurust
  • fill the area with filler - layer it if the application needs to be deep
  • sand the area back, sand it again, and again... get finer and finer with your sanding till you wet n dry - use a sanding block
  • mask everything and anything you can (including yourself!)
  • prime
  • sand
  • prime
  • sand - repeat prime and sand until you are happy with the finish
  • wet n dry
  • wash it down
  • tack cloth - literally tacky cloth
  • test spray on an old bit of metal - spray off the area and then across - repeat this process until you have your technique down (will pay dividends later)
  • make sure your spraying area is warm, clean, dry, dust free, windless - really advise against doing this outside  - inside in a large well ventilated dust free environment is best esp at this time of year
  • shake the can well, then shake the can well, then shake it again etc - you get the picture
  • spray by building up the layers of paint - take your time over this
  • lacquer is good for a good finish but only if your paint is finished well
  • let the paint dry and harden over a two week or so period and then cut it back to match in with the surrounding paint
  • then apply a wax to protect

the paint you can get your dealer to mix up and they do a touch up kit with a lacquer for about 12/15 quid i think - you just need to give them your paint code

you can get halfrauds to mix up the paint too i think but i don't know about the quality

90% of getting this job right is in the preparation... take short cuts in the prep and it'll show through from a mile

please anyone feel free to correct me if you feel this advice is incorrect or can be improved upon

That doesn't really answer my questions. I need specific materials.  :wink:

C'mon Shady :rolleyes:

Assuming you don't have to worry about paint:

  • grind the area back to metal - take your time doing this and do it gently - Grinder & Discs
  • treat the metal with rust stuff like kurust - Kurust
  • fill the area with filler - layer it if the application needs to be deep - Filler
  • sand the area back, sand it again, and again... get finer and finer with your sanding till you wet n dry - use a sanding block - Sanding Paper/Wet&dry & Block, I'd start with maybe 400grit and work your way upto 2000, others may disagree thought,
  • mask everything and anything you can (including yourself!) - Masking tape
  • prime
  • sand
  • prime
  • sand - repeat prime and sand until you are happy with the finish
  • wet n dry
  • wash it down
  • tack cloth - literally tacky cloth - Tack Cloth
  • test spray on an old bit of metal - spray off the area and then across - repeat this process until you have your technique down (will pay dividends later)
  • make sure your spraying area is warm, clean, dry, dust free, windless - really advise against doing this outside  - inside in a large well ventilated dust free environment is best esp at this time of year
